SASH FA STENER AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 573,439, dated December22, 1896.

Applicatidn filed July 31,1896, $erial No. 601,127. (No model.)

To ctZZ whom, it may concern.

. Be it known that I, J AMES BENJ. OAHooN,

New York, have invented certain new and useful Improvements inWindow-Sash Fasteners and Supports,of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof, in which similar letters of reference indicatecorresponding parts.

This invention relates to an improvement in window-sash fasteners andsupports, the

means for automatically locking and supporting windows, whereby thenecessity of using ropes and weights is obviated.

The invention will be hereinafter fully described and specifically setforth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure1 is a front elevation of aportion of the window-frame having myimproved device attached thereto. Fig. 2 is an inverted sectional plantaken on a line 00 0c of Fig. 1. Fig. 3is asectional plan view taken ona liney'y of Fig. 1, and Fig. 4 is a sectional plan view taken on a line.2 e of Fig. 1.

In the practice of my invention the upper sash A and the lower sash Bare both provided, respectively, with grooves a and b throughout nearlythe entire length of the right-hand vertical portion of their frames.Into these said grooves are secured racks O, which said racks engagewith pinions D. These said pinions are connected to beveled gear-wheelsE, and these said beveled gearwheels engage with other beveledgear-wheels F, all of the said parts being mounted within casingsG,'which are set within recesses g of the window-frame A. The pinions Dand their beveled gear-wheels E are journaled upon shafts d, and thebeveled gear-wheels Fare mounted on shafts f, which said shafts farejournaled within the side walls of the casings G. Secured also to theshafts f are coiled springs H, which said springs are normally in anunwound or loose condition, and their free ends are attached to pins hof the casings G. These said springs are adapted to retain the windowsin position, as will be hereinafter described. A

Located within recesses of the upper and lower sash A and B,respectively, are casings :I, and mounted within these casings arelongitudinally-movable spring-pressed bolts J, which said bolts arenormally maintained in outward positions by means of springs J, and theyare adapted to engage with recesses a of the window-frame A, and whenthe windows are closed these said bolts will automatically engage withthe said recesses for locking the windows. object thereof being toprovide an efficient I As a means for fastening the bolts and retainingthem in an unlocked position, as illustratedin the upper sash in Fig.lof the drawings, I provide spring-pressed pawls K, which engage withprojections of the bolts J, and as a means for operating the said boltsJ or unlocking the same I provide levers L and L, respectively, foroperating bolts of the upper and lower sashes. These said levers arejournaled upon pins Z, which are secured to the casings I.

The lever L for operating the bolt of the upper sash is provided uponits inner end with a slot Z, which engages with a pin j of the bolt J.The outer end of the lever L engages with a rod M, which passeslongitudinally through the vertical framework of the sash A, whereby thebolt may be released from its recess Ct for unlocking the window when itis desired to lower the upper sash.

The lever L for operating the bolt J of the lower sash is connected atits inner end to a toggle-lever Z which engages with a pin of the boltJ. This said lever L has its end extended through the front of thevertical framework of the lower sash, whereby the bolt J may be operatedfor unlocking the window when it is desired to raise the said lowersash.

In the operation of the device with relation to the lower sash when itisentirely closed or lowered, as illustrated in Fig. 1 of the drawings,the pawls K will be thrown out of engagement with the projection j ofthe bolt J by means of the said pawls contacting with the pinionB,whereby the bolt will be released and its spring J will automaticallyshoot it into its recess a, thus locking the window. When it is desiredto raise the window, the bolt J willbe thrown into position (illustratedin Fig. 3 of the drawings) by means of the lever L. The pawl K will thenspring into engagement with the projection j of the bolt J and maintainthe same in an unlocked position until the window is again lowered to adepth sufficientto allow the pinions D to throw the pawl out ofengagement with the stop or projection j. The operation of locking andunlocking the upper sash is precisely the same, with the exception thatthe lever L is operated through the medium of the rod M.

The springs H are normally in a looselywound condition, and the act ofwindin g them respectively by the action of lowering the upper sash andlowering the lower one will cause the windows to be maintained in anydesired open position without the means of either ropes or weights.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a sash fastening and hanging apparatus, the combination of apinion and beveled gearing and a coiled spring located within thewindow-frame and a Vertical rack upon the edge of the window-sashengaging with the said pinion and beveled gearing, and a springpressedbolt also located within the windowsash and means for automaticallyoperating said bolt comprising a spring-pressed pawl which engages withthe pinion of the said gearing of the frame and with a projection of thesaid bolt, substantially as shown and described.

2. As a means for fastening and hanging windows, the combination of aVertical rack secured Within the edge of the window-sash and a pinionengaging with said rack secured within a recess of the window-frame,said pinion being in engagement with a beveled gearing,which gearing issecured to a coiled spring for maintaining the sash in position; with aspring-pressed bolt which is secured within a recess of the sash and aspring-pressed pawl for engagement with the said bolt, said pawl adaptedto be automatically operated by means of the said pinion, and means forindependently operating the bolt comprising a lever attached theretowhich leads through the framework of the sash, substantially as shownand described.

In testimony that I claim the foregoing as myinvention I have signedmyname, in presence of two witnesses, this 28th day of July, 1896.
